COOLING-BOARD.

SPECIFICATION formingpart of Letters Patent No. 746,223, dat d D b f 8,1 903. Application filed October 4} 1901. Serial No 77,626. (No model.)

sion of a novel construction of cooling board,

such as is used by undertakers, and has for its objects, primarily, areduction in the bulk and weight of the board, and improvement in thestiffness and strength thereof, and a simplification of the structure ingeneral, all as will more clearly appear in connection, from.

an examination of the accompanying drawings illustrating my invention inpreferred form, and in which,

Figure 1 is a plan view of my improved cooling board when expanded inoperative position;

Figure 2 is an inverted plan view of the same, showingthe main frame andleg braces in position;

Figure 3 is a side elevation, with the parts in operative position;

Figure 4 is an end View with the parts in operative position; t

Figure 5 shows an end view of the device folded ready for transportationor carrying; Figure 6 shows a detail of one of, the legs and the socketthereof;

Figure 7 is a detail showing a part of the leg bracing; v

Figure 8 is asectional view of one of the legs; Figure 9 shows one ofthe improved brace locks which I employ;

Figure 10 is an end elevation, partly in section, showing myim provedform of head-rest; and l Figure 11 is a side view of the head-rest.

Referring now more particularly to Figures 1 to 5 inclusive, it will beseen'that in carrying out my invention I provide a structure comprisinga plurality of pivot'ally connected parts or sections forming what maybe called the table of the board, which I have marked 12, the partsthereof beginning at the left in Figure 3 being marked respectively 1212 12, 12, 12", 12 12 and 12 Eachof the parts or sections referred tocomprises a flat or horizontal portion 13, preferably of wood (whichmaybe perforated for lightnessif desired, as shown at 14 in Fig. 2),

and a downwardly projecting rib or strengthening part 15,.the said ribs15 being the means Y whereby the several sections are pivotallyconnected together byk'nuckle joints, and comprising as a wholewhatlhave termed the frame of the board.

A short distance from'each end of the board there are secured to theribs .15 leg sockets 16 which are preferably square in cross-section andembrace or contain slidable leg extensions 17 which serve to adjust theheight of the board. On opposite sides of each pair of legsockets arearranged .a pair of joint-ed braces 18 and 19 extending across the boardso as to stand, when erectedin' position, ap-- proximately at rightangles with each other (see Figure 4), the free ends of said bracesbeing provided with hooks 20 which engage with pins 21 that, passingthrough slots 22 in the leg sockets, are secured firmly in the legextensions 17 (see Figures 7 and 8). The hooks 20 are provided withsliding latches 23 (see Figure 9) so as to prevent their droppingont ofplace when the board is in operative position.

The .legs are further braced longitudinally of the board by means ofbraces 24 and 25,

which are preferably attached'to theiribs 15 24, 25 are provided-withhooks 27 which engage pins 28 in the leg sockets 16, each pair of thesebraces being providedwith a pivotcdlatch device 29 (see Figure 7) forholding them from dropping out of" place when the board is in operativeposition. The leg sockets 16 are pivotally'mounted in U-shaped pieces 30secured to the ribs 15 (see Figure 6), the pivot pins 31 for such piecesbeing also utilized as pivots for the base ends of thebraces 18 and 19inthe leg sockets 16.

Referring now more particularly to Figure 3, it will be seen that at oneend of the board,

parts 12 and 12 which are knuckle-jointed to each other are constructedso as to be capable of elevation into an inclined position, the degreeof such elevation being determined by the notched segments 32 whichengage the pins 33 which are secured to the frame parts 34 that at thisend of the board form practically a continuation of the ribs 15, therebeing at this end of the board on each side thereof an extra rib partfor the three clamps 12 12*, and 12 (see Figure 2), in order that theseparts maybe raised to the inclined position, as shown.

. Referring now more particularly to Figures 3 and 5, it will be seenthat, beginning at the right, the parts comprising the table 12 are ofdifferent widths; thus, for example, 12 is wider than 12 and 12 is widerthan 12*, this provision being for the purpose of making it possible tofold or roll up the device after the leg braces have been taken down,and the legs folded against the table into the position shown in Figure5, so that the whole apparatus may be placed in a telescope or ordinarycase about the size of a dress suit case so as to be easily andinconspicuously carried about.

Another feature of my improvement has reference to the novel form ofhead rest which I employ, which is clearly shown in Figures 10 and 11,inwhich thereisacurved head piece 35 adapted to rest against the back ofthe neck of the subject, said piece being provided with a ball 36,socketed at 37 in the upper end of a post 38 which extends through theboard and is formed with an adjustable latch 39 constructed to hold thehead-piece at anyelevation desired. The ball and socket joint for thehead piece is provided with a looking or thumb screw 40 to hold it fixedin any position in which it may be set. By this means it is madepossible to manipulate the subjectin any manner desired with greatconvenience, and a minimum expense of time, the device beingparticularly useful for shaving operations.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. A cooling board composed of knucklejointed sections and foldablesupports for the same, the said sections being arranged in two series,the sections of one series alternating with the sections of the otherseries, and the sections in each series progressively increasing inlength so that all the sections may fold compactly around each other.

2. A cooling board composed of a series of knuckle-jointed, alternatelylong and short, sections, both the set of long and the set of shortsections respectively being progressively increasing in length, so thatall the sections may fold compactly around each other with the saidshort sections covering the ends of the long sections, as described.

3. In a cooling board, the combination of a foldable set ofknuckle-jointed sections progressively increasing in length each joinedin alternation with one of a set of shorter sections, also progressivelyincreasing in length, with jointed legs for said board and foldablebracing rods for said legs.

4. The combination of a foldable cooling board divided into two seriesof alternating sections the sections of each series being ofprogressively increasing lengths, an end section provided with a notchedbrace for alteringits inclination, fold-able legs provided with meansfor adjusting their length, and jointed diagonal braces capable offolding under the end sections of the board, substantially as described.

5. A cooling board composed of a series of CHARLES E. WINDOM.
